<p>A pulping apparatus for mixing fibrous stock materials for recycling thereof, comprising a vessel having a passageway therethrough defined by an inlet (12) opening and an outlet opening. The vessel includes a rotatable axial shaft disposed in the passageway, and a series of cooperating propeller members being arranged in offset radial relation to effect continuous flow of the pulp slurry through the passageway of the vessel. The pulping vessel of the invention is designed to minimize breakdown of the ink, stickies and contaminants in wastepaper while at the same time providing sufficient mixing action to allow them to contact each other for agglomeration. The invention also includes related deinking processes employing the aforementioned apparatus.</p> |
